The importance and application of aluminum die casting

Aluminum die casting is a pressure casting part.The liquid aluminum or aluminum alloy poured into the pressure die casting machine is casted as parts of aluminum die casting.Aluminum die castings are widely used in automotive casting,electrical casting,pump casting parts,precision casting,motor casting and so on.

Aluminum die castings are lightweight; yet withstand the highest operating temperatures of all the die cast alloys. Its strength, rigidity, and corrosive resistance offer significant heat dissipating advantages.

Aluminum is used in a broad range of networking and infrastructure equipment in the telecom and computing industries. Aluminum castings work for this application because RF filter boxes and housings require heat dissipation. It also provides EMI shielding, rigidity and durability with minimal weight for shields and housings for handheld devices. Because of aluminumís excellent electrical performance and shielding properties, even in high-temperature environments, die casting aluminum is ideal for electronic connectors. Fotaiís proprietary Thin Wall Aluminum Technology has made aluminum die casting an option for more applications.

Aluminum die castings improve automotive fuel efficiency by contributing to weight saving requirements. Our strength is in electronic applications, such as shields for telematic equipment and sensor housings, and safety-critical occupant restraint systems such as airbag housings and seat belt retractor spools.

Aluminum alloy characteristics:

Highest operating temperatures;

Outstanding corrosion resistance;

Light-weightVery good strength and hardness;

Good stiffness and strength-to-weight ratio;

Excellent EMI & RFI shielding properties;

Excellent thermal conductivity;

High electrical conductivity;

Good finishing characteristics;

Full recyclability.

Alloys of aluminium are used in die casting more extensively than alloys of any other base metals.Die casting is especially suited to production of large quantities of relatively small parts. The more important reasons for using light metal casting are low weight, mechanical strength, stiffness and electrical properties. Other applications are e.g. components for the power transmission line in the vehicle industry and electronics industry.

With die casting, it is possible to maintain close tolerances and produce good surface finishes. Die castings are made by injection of molten metal into metal molds under substantial pressure. Rapid injection and rapid solidification under high pressure combine to produce a dense, fine-grain surface structure, which results in excellent wear and fatigue properties.
